Keswick Dam is a concrete gravity dam on the Sacramento River about 2 miles (3.2 km) northwest of Redding, California. Part of the Bureau of Reclamation's Central Valley Project, the dam is 157 feet (48 m) high and impounds the Keswick Reservoir, which has a capacity of 23,800 acre·ft (29,400,000 m3). Its powerplant has three turbines with a generating capacity of 117 megawatts (MW) uprated from its original 75 MW in 1992. The dam and reservoir serve as a forebay to regulate peaking power releases from the Shasta Dam upstream. The electrical substation at Keswick Dam distributes power not only from the Keswick powerplant but also from powerplants at Trinity Dam and Lewiston Dam, as well as the Judge Francis Carr Powerplant near Whiskeytown Lake and the Spring Creek Powerplant, located just northwest of Keswick Dam.
